Are we all related? Finding the Most Recent Common Ancestor

Показать описание
The most recent common ancestor or MRCA is the common ancestor from where a set of individuals are directly descended. You grandfather is the MRCA of you and your cousin; your great grandfather is the most recent common ancestor of you and your second cousin and so on. In this video I explore the ground breaking work done by L. T. Rohde, Steve Olson & Joseph T. Chang. They created complex models that took historical human migration routes into account to identify the human we are all descended from. The results of their calculations are quite surprising as I explain in the video.

I don't get this. You're saying the MRCA of every person alive today lived before around 1000BC? That can't be though as Aborigines in Australia arrived there over 60, 000 years ago. How can they trace their ancestry back to the MRCA from 1000BC?
